If you've gotten a perma ban and you're trying to appeal...
Ask yourself this : Would you say what you said in your past 20 games to someone at work? Would you be upset if someone else said those things to you? Were you trolling/throwing/the actual reason your team lost? Did you actually work with your team or were you just harassing them? Have you said any racial slurs/sexist terms?
Most people will blame their teammates in a heartbeat. I know there are trolls, afks, feeders. There is that one guy no matter what rank you are. I'm not saying you can't be mad. I get mad too. But I don't get mad the the point where I say shit like "you fking ni*** fking jews". And I've noticed the majority of people who have gotten banned have said things like that multiple times.
